31日从国家能源集团了解到，位于四川阿坝州的世界第一高坝——大渡河双江口水电站一期三台机组全部投产发电。

On the 31st, the National Energy Group informed that the first-of-its-kind high dam in the world - the Dagua River Shuangjiangkou Hydropower Station - has successfully put into operation all three units of its first phase.

位于四川境内的双江口水电站是国家重点能源工程，大坝坝高315米，为当今世界第一高坝。电站总装机容量200万千瓦，共安装4台单机容量50万千瓦的混流式水轮发电机组，水库总库容29亿立方米，是大渡河上游兼具防洪、发电、水资源调配功能的控制性龙头工程。

The Shuangjiangkou Hydropower Station, located in Sichuan Province, is a key national energy project. The dam is 315 meters high and is currently the world's tallest dam. The total installed capacity of the power station is 2 million kilowatts, and it is equipped with 4 single-unit generators with a capacity of 500,000 kilowatts each. The total reservoir capacity is 2.9 billion cubic meters. It is a controlling and leading project in the upper reaches of the Dadu River, with functions including flood control, power generation, and water resource allocation.

自今年6月首台机组投运以来，建设团队紧扣成渝经济圈高温用电保障需求，两个月内高效完成三台机组接续投产，累计输送清洁水电5亿千瓦时，有力夯实了四川省及成渝经济圈夏季电力保供基础。

Since the first unit was put into operation in June this year, the construction team has closely adhered to the high-temperature electricity demand of the Chengdu-Chongqing economic circle. Within two months, they successfully completed the consecutive commissioning of three units, with a total of 500 million kilowatt-hours of clean hydropower being delivered, effectively laying a solid foundation for power supply guarantee during the summer in Sichuan Province and the Chengdu-Chongqing economic circle.

电站全部机组投产后，年均发电量约77亿千瓦时，每年可为下游梯级电站群增加66亿千瓦时发电量增益，将持续提升大渡河流域水资源综合利用效率。

After all the units of the power station are put into operation, the annual average power generation will be approximately 7.7 billion kilowatt-hours. Each year, it can provide an additional 6.6 billion kilowatt-hours of power generation benefit to the downstream cascade power stations, and will continuously enhance the efficiency of water resource utilization in the Dadu River Basin.
